Disclosed is a method for synthesizing sapropterin dihydrochloride. The present disclosure reduces a synthesis route of the sapropterin dihydrochloride, and resolves a racemate intermediate or an intermediate having a low antimer isomerism value by using a chiral resolving reagent, thereby obtaining an intermediate having a high antimer isomerism value. Raw materials are cheap and readily available, and the cost is significantly reduced, hence providing an effective scheme for mass industrial production of the sapropterin dihydrochloride.
公开了一种合成盐酸沙普曲酮的方法。本公开通过使用手性分离试剂减少了盐酸沙普曲酮的合成路线,并解决了一个具有低对映异构体值的混合物中间体或中间体,从而获得一个具有高对映异构体值的中间体。原材料价格便宜且易得,成本显著降低,因此为盐酸沙普曲酮的大规模工业生产提供了有效方案。
